Alright guys im ready to purchase some in the next few days, just wondering from anyone who has bought VIA ebay. If you purchase them with optics, are they easily removed if I choose not to use them? OR What should I be looking for.

I know i need 3 fixtures as my tank is 72x20x20 and im going to be going for the Whites/Blues only. I was thinking I may end up emailing the guy at reef breeders for a cost to ship to Canada but I might end up going the ebay route. Either way just like to know what style of optics I should be looking for.

If you can't fix it with a hammer, you have an electrical problem!

Your going with 3 over a 6 foot tank? Sounds like ill be able to do the same. I know some ebay sellers ship from the usa to canada. And i wouldnt have a clue about the optics. I think they come installed and thats that. If your going with 3 on that tank, 90 degree or 120 or 130 would be good optica 90 probably the best bet
